Nice Cool Night Ahead Humidity Heat Return Over The Weekend
Now that today’s interruption of the nice weather is over with, the upper trough is offshore and skies are clearing out. This is setting us up for a nice cool night across the region with most lows in the mid 50s to lower 60s. Even the warmer urban centers will get below 65 overnight. Low humidity means comfortable conditions overnight and that will last probably into early Friday morning. Thursday is going to be a nice day with plenty of sunshine. Highs will reach the upper 70s and lower 80s. The radars are now quiet and will remain so through Thursday.
The dry high begins to move offshore Thursday night but it should remain comfortable with clear skies and lows in the upper 50s to mid 60s. Friday starts a flow from the south which will bring up the humidity somewhat but it will still be reasonably comfortable. Highs Friday will be in the low to middle 80s. We will see a fair amount of sunshine.
Saturday turns very warm and more humid with some sunshine and the chance for a scattered shower or thunderstorm. The same holds for Sunday. Saturday’s highs will be in the mid to upper 80s. Sunday’s highs will be in the upper 80s to around 90 degrees in some places. There is also the chance for a scattered shower or thunderstorm on Sunday.
It looks as if it will be very warm to hot and humid for the first part of next week. We may get a slight humidity break on Monday but only slight with highs again reaching the upper 80s to near 90. The very warm somewhat humid weather will carry into midweek before the next important cold front begins to approach.
TROPICAL WAVES GETTING BETTER ORGANIZED
There are two tropical waves of interest in the Atlantic basin that are front and center this evening. The first is in the Central Caribbean and it has show signs of organization this evening. The second in the tropical Atlantic has become better organized. Low pressure has developed there and if the circulation tightens up a bit overnight we could have a tropical depression or a tropical storm on the map Thursday. Both systems are heading west to west northwest and they will stay on this heading for the next several days. The Caribbean system is destined for the Gulf of Mexico. The other will track toward the Leeward Islands.
The Caribbean system shows a wide spread in the tracks making forecasting intensity a bit difficult. It would seem a favorable outflow pattern will develop here and it deserves watching closely. The Atlantic system has a different problem.
Many of the models including the global models take this right over all the big islands in the Greater Antilles. This would limit development considerably until the system gains some clearance from those islands to the north. Much uncertainty lies here regarding its future so the best we can say at this point is that we will watch the high to the north. If it is a little weaker than forecast, it could nudge the system further north and keep it over open water allow it to strengthen.
